Title: Improvements in or relating to control arrangements for fluid pressure actuated single acting pistons
IPC: F15B11/04
Filed: 1951-09-19
Abstract: 750,389. Engine valve-gear. ZOLLER, H. Sept. 19, 1951 [Nov. 21, 1950], No. 5499/55. Divided out of 750,293. Class 122(2) In a fluid-pressure actuated engine comprising a single-acting piston working in a cylinder 14 pressure fluid is admitted to and exhausted from the cylinder 14 by separate inlet and exhaust valves 18 and 26 respectively operated by fluid pressure controlled by a main control valve 4 combined with the piston 15. The valves 18 and 26 are respectively loaded to close and open by springs 22 and 29 and the valve 18 has a lower part 18a which co-operates with a gasket 21 to form a closure. Pressure fluid from a source T flows through a throttle valve 2 and conduits 9 and 23 respectively to the main control valve cylinder 3 and the underside of part 18a and, at the beginning of a cycle of operations, passes through the opening in gasket 7 in the cylinder 3 and a conduit 10 to cause the inlet valve 18 to move downwards and open the port in the gasket 21 and the valve 26 to close the exhaust port 28. Fluid then enters the cylinder 14 via conduits 24 and 25 and pushes the piston 15 to the right until the valve 4 seats in the gasket 7 and opens an outlet port 11 in a gasket 8 thereby exhausting the pressure ir. conduit 10 to atmosphere and allowing valves 18 and 26 to return to their original positions. The piston 15 is returned by a spring 12, or a counter-piston 37 operating in a cylinder 36 supplied with fluid through a conduit 35, and cylinder 14 is exhausted through port 28 until the valve 4 again opens the port in gasket 7 and closes the outlet port 11 and the cycle recommences. To allow the piston 15 to pause at the end of a return stroke fluid is supplied to the valve 18 through a valve 31 seating on a seat 32 and provided with a small inlet bore 33 and several larger outlet bores 34. A power drive for a pump 45 or any other apparatus may be taken from an extension 44 of the counter-piston or from a member 39.

The finishing tools are secured by screws 19, and are arranged at progressively decreasing radii and with their tips at progressively increasing distances from the cutter face. Thus in Fig. 3 the surface 23 has been roughed by the roughing tool, and the surfaces 24, 25 cut by two different finishing tools. When two roughing tools are used they may be located close together with their edges at different distances from the cutter face or at different distances from the cutter axis. Specification 534/15, [Class 83 (iii)], is referred to.
Patent GB-629117-A (GB)
Title: Improvements relating to bimetallic elements
IPC: G01K5/66
Filed: 1947-02-26
Abstract: At least one member of a bimetallic or multimetallic temperature responsive element (see Group XIII) is made of an alloy which is age-hardened and also nitrided throughout its cross-section.  The alloys thus treated may have a nickel-iron base or be a copper-nickel-manganese alloy and contain not more than 80 per cent of elements such as nickel, copper, chromium, molybdenum and tungsten (since these do not impart nitridability) but contain 20-97 per cent of nitriding promoters such as titanium, manganese, silicon, aluminium and iron.  Age-hardening elements may be titanium, aluminium, silicon, beryllium or magnesium or (for copper base alloys) manganese.  Iron alloys are defined containing 40.5 to 53 per cent nickel, 41 to 43 per cent nickel and 4.5 to 6.5 per cent chromium and 28 to 30 per cent nickel and 8 to 9 per cent chromium each with small amounts of titanium, aluminium, silicon and manganese.  Cupro-nickels containing 30 to 45 per cent nickel and 55 to 70 per cent copper and nickel-copper alloys containing about two-thirds nickel and one-third copper are instanced as alloys suitable for a member to be untreated.  Since the age-hardening can consist of keeping the alloy between 1700 and 1850 DEG F. for at least twenty minutes, followed by quenching and then heating within a range of 1100 to 1350 DEG F. for 3 to 48 hours and the nitriding can consist of treating the alloys between 900 and 1200 DEG F. in ammonia of 24 to 40 per cent dissociation, it is possible to perform these treatments simultaneously e.g. at temperatures of from 1100 to 1200 DEG F.  The Specification as open to inspection under Sect. 91 gives as examples of the latter, alloys containing 26 to 33 per cent copper and 63 to 73 per cent nickel and, if the member is to be age-hardened but not nitrided, aluminium and/or titanium may be present.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to electrical devices employing piezoresistive elements
IPC: G01P15/12
Filed: 1960-02-17
Abstract: 940,730. Piezo-resistive accelerometers. WESTERN ELECTRIC CO. Inc. Feb. 17,1960 [Feb. 18, 1959], No. 5639/60. Heading G1N. In an accelerometer a single unitary indicating element comprises a central mass with one or more pairs of collinear legs cut from a single crystal of a piezo-resistive substance, which legs are so orientated with respect to the crystallographic axes that the electrical resistances between the respective legs of a pair and an ohmic contact on the central mass vary oppositely when one leg is put under compression and the other under tension. Construction of transducer; Fig. 6 shows an element cut from a single silicon crystal and comprising a spherical central mass 60 and three mutually perpendicular pairs of collinear projecting legs 61, 62; 63, 64; and 65, 66, which are as thin as is compatible with strength and which are attached at their outer ends by enlarged feet to a rigid framework 70, 72. Modifications with two pairs and one pair of legs are described; and the legs may be secured directly to a vehicle instead of to a frame. Details are given as to the proper orientation of the legs in relation to the crystallographic axes in accordance with the material of the semi-conductor. The mass of the central sphere may be increased by loading it with lead, resin &c. Circuit arrangements; Fig.7. The resistances between the respective legs of a pair form adjacent arms, e.g. 161,162 of an A. C. bridge circuit, with an indicator such as 40 showing the component of acceleration in the direction concerned. To compensate for the fact that in practice an acceleration in the direction of one pair of legs may cause resistance variations in the circuits associated with the others, each bridge output diagonal has an adjustable coupling with the output diagonals of each of the other bridges. To remove ambiguity as to the sense of the acceleration, when using a simple circuit with an element having only one pair of legs, an additional meter 208, Fig. 9, sensitive to phase sense may be associated with each input diagonal. Alternatively D.C. bridges may be used. Modifications. Combinations of the single pair of legs elements, suitably orientated, or the double pair of legs form may also be used to obtain response to coplanar multidirectional accelerations. Specifications 881, 832 and 881, 834 are referred to.

Title: Conveying apparatus
IPC: B61B9/00
Filed: 1950-03-07
Abstract: 744,292. Conveyers, electric railway systems. BURGH, A. R. DE. March 7, 1950 [March 10, 1949], No. 5742/50. Classes 78 (1) and 104 (3). In conveying apparatus having carriers arranged to run outside a hollow guideway, blocks having magnetic means associated therewith are slidably located within and driven along the guideway and are arranged to co-operate with magnetic means on the carriers to cause the carriers to be moved with the blocks. Carriers 10 are mounted on rollers 11 to travel along a table 12. Each carrier has centrally placed on its underside a piece 20 of magnetic material which is positioned close to the table 12. In a trough 13 below table 12 are a series of blocks 15 secured to an endless travelling cable 14 and guided by rollers 17 on their sides. A magnet 16 is mounted in the block 15 which attracts the piece 20 through the table 12 which is of non- magnetic material. Instead of a permanent magnet 16 an electromagnet 22, Fig. 6, may be used, which is energized through sliding contacts 23. The piece 20 may be replaced by a magnet 25 arranged with opposite poles facing the poles of the electromagnet. The piece 20 may alternatively be hinged to the carrier to closely follow the surface of the table 12. The blocks 15 are driven by a wheel whose teeth have grooves for the cable 14. In a modification, Fig. 9, the carriers 10 run on a concrete bed 40 in which is embedded a guideway 41 along which travels a series of blocks 43 threaded on a cable 48. Some of the blocks carry magnets whilst each block is provided with lugs 45 co-operating with recesses 42 in the guideway. The guideway can follow a path curved in both horizontal and vertical planes, the blocks having co-operating spherical end surfaces formed on their ends for this purpose. In a further modification, Fig. 11, a guideway is formed from two U-section girders 61 embedded in concrete 60 so as to leave a gap between them. Blocks 62 threaded on a cable have spherical end faces and a lug 63 along their upper face. By inserting magnets in these lugs the poles of the magnets can touch or nearly touch the bars of magnetic material on the carriers 10, giving a stronger force of attraction. In use, the carriers 10 are placed in position to co-operate with the moving magnets and removed from the conveyer by pulling them sideways. Specification 744,297 is referred to.

Title: Improvements in or relating to internal combustion engine power gas plants
IPC: F02B71/06
Filed: 1945-03-09
Abstract: 600,509. Elastic-fluid turbines. SULZER FRERES SOC. ANON. March 9, 1945, No. 5897. Convention date, March 10. 1944. [Class 110 (iii)] [Also in Group XXVII] An Internal-combustion engine power gas producer plant has a blow-off valve for the power gas and a device which varies the closing force acting on the blow-off valve in accordance with a service value of the plant in such a way that at least within a part of the working range of the gas consumer this closing force lies by an adjustable amount above the force tending to open the blow-off valve due to the pressure of the power gas thereon. By " service value " is meant some value which varies in accordance with changes in operation or output of the plant, e.g. the speed of a turbine driven by the power gas. In the plant shown, free piston gas generators 1, 2 supply combustion products through shut-off valves 12, 13 to a main 16 and blow-off valves 18, 19 are provided. The closing force on the blow-off valves is controlled by the governor of a turbine 17 driven by the combustion products in such a way that the closing force is normally slightly above the force due to the combustion products tending to open the valve. As shown, the blow-off valves are controlled by springs 20, 21 acted on by members 22, 23 carried by levers 24, 25. The pressure on the spring can be varied by hand by adjusting screws 28, 29 which vary the position of pivots 26, 27 of the levers. Automatic variation of the load on the springs is obtained by cams 32, 33 worked by the governor 36, of the turbine normally to keep the closing force above the opening force due to the pressure of the combustion products. If it is desired to cut out one of the generators, this is done by closing a cut-out valve 12 or 13. Since the load closing the blow-off valve is only slightly above the load tending to open the valve, as soon as the cut-out valve is closed, the pressure rises sufficiently to open the blow-off valve and prevent stalling of the generator. In an alternative arrangement, Fig. 3 (not shown), the governor acts through a relay device. The construction shown in this Figure is the same as that in Fig. 1 of Specification 600,510, and further details are given in the abridgment of this Specification. The same Figure also shows an arrangement for closing a cut-out valve in the event of the stopping of a gas producer. The air supply to the compressors of the gas generators may be supercharged preferably by a rotary compressor driven by a gas turbine driven by the products produced in the plant. The invention is not restricted to free piston gas generators, but may be applied to other internal-combustion gas generators. There may be one only blowoff valve for a number of generators or each generator may have one in addition to a main blow-off valve .for a plant. The manner of switching in a gas producer is described. Specification 455,358 also is referred to.

Filed: 1917-04-27
Abstract: 112,223. Andrews, J. April 27, 1917. W a t e r , distilling. -- In apparatus for marine or land use for obtaining cold or hot distilled water, steam, such as waste steam from auxiliary machinery, is passed through coils in an evaporator 1 supplied with sea or other water through a valve 5. The steam generated in the evaporator passes through a pipe 8, a heat-exchanger 9 for heating the water supplied to the evaporator, and a h e a t - exchanger 7 for heating water for boiler-feed or o t h e r purposes. The hot condensed water passes into a drainvessel 12 from which it is run either through a pipe 17 and a cooler and filter 18 to a storage vessel 20, or through a pipe 15 to a hot-water tank 16 or through a pipe 13 to a hot-well 14 which also receives the steam and condensed water from the coils of the evaporator. The evaporator-feed heater 9 may be omitted or may be placed in the pipe connexion 17. Two or more evaporators which may be arranged for multiple effect may be used.

Abstract: 730,684. Hydraulic shock absorbers. MORRIS MOTORS, Ltd. Dec. 14, 1953 [March 4, 1953], No. 5973/53. Class 108 (3). The part of the recuperation chamber of a telescopic hydraulic shock absorber, which becomes hottest during operation, is provided with external secondary heattransfer surfaces constituted by an assemblage of metal fins 12, the flanges 12a of which, serve as spacing means for the fins, and afford a greater area of contact for conduction of heat from the chamber to the fins. The fins may be of elliptical, square, or annular, shape. According to the Provisional Specification, the heat-transfer surfaces may comprise metallic foil, gauze, braid, or coiled wire. The foil &c. may be formed with corrugations disposed axially of the shock absorber. Alternatively, the casing of the shock absorber may be corrugated, and may be surrounded by a metal cylinder. Air may be pumped along the channels formed by the corrugations by the action of the usual dust-excluding sleeve carried by the piston rod, or by a rubber bellows. In the latter case, the foil &c. may be replaced by cooling fins, which extend the whole length of the recuperation chamber. The inner edge of each fin is recessed at intervals to accommodate longitudinally-extending air ducts.

Title: Improvements in or relating to variable jet nozzles for jet propulsion units
IPC: F02K1/15
Filed: 1945-03-09
Abstract: 598,184. Fluid pressure servomotorcontrol systems. LOMBARD, A. A., and GRIMWOOD, M. V.. and SKIPWITH, G., [Representatives of COURLAY, G. K. L.]. March 9,1945, No. 5988. [Class 135] A variable jet nozzle for a jet propulsion unit is adjusted by a hydraulic ram 9 supplied with pressure liquid from a pump 10 under the control of a valve 13, itself controlled by a temperaturesensitive device 16 in the jet pipe, the supply of pressure liquid also being controlled by a follow-up device actuated by the ram to prevent hunting. As shown, a spring-loaded valve piston 14 is actuated by pressure liquid being admitted to or allowed to escape from a chamber at the left-hand end of the piston according to the position of a further spring- loaded piston valve 23 actuated by the temperature-sensitive device. In operation, should the temperature in the jet pipe change to move the valve 23, say, to the right, pressure liquid will act on the piston 14 to move it to the right, thereby admitting pressure liquid, by a conduit 19, to the ram vhilst venting a conduit 20, the consequent movement of the ram adjusting the nozzle by moving a pair of sector-members 6 about a pivot 7, and also,cutting off the supply of liquid to the ram after a certain displacement corresponding to the displacement of the piston 14, by moving a ported sleeve 17 constituting the follow-up device. A temperature change in the opposite sense results in a reduction of the pressure acting on the piston 14, allowing the latter to be moved by its spring to effect movement of the ram in the other direction. In a modification, the temperature-sensitive device acts directly on the piston 14 through a lever. Specification 598,182 is referred to.

Feb. 27, 1928 Charging; covers.-In a cupola furnace having an offset chimney 5 and a central charging opening 2 closed by a movable cover 3, the latter is operated by or in conjunction with the charging bucket 14 to open and close the furnace as the bucket approaches and recedes from its position over the charging opening 2. Fig. 3 shows a construction in which the cover 3 is carried by a pair of counterweighted pivoted arms 17, the ends 17A of which are adapted to be engaged by rollers 24 mounted on the end of rods 23 pivoted to the bucket 14. The rods 23 are also formed with members 26 which engage flanges 22 on the arms 17 to effect a positive closing of the cover 3 as the bucket moves away from the opening 2. A buffer 27 is provided to cushion the opening movement of the cover and a similar buffer mav be provided to check the cover as it approaches its closed position. The bucket 14 is raised and lowered by tackle 14A carried on an arm 13 secured to a mast 10 which is rotatably mounted in bearings 11, 12 on the outer casing on the furnace. In a modification, the arm 13 is replaced by a lever pivoted at its centre about a horizontal axis, the lifting tackle 14A being carried on one side of the pivot and the cover 3 being suspended from the outer end of the opposite arm of the lever. Fig. 6 shows a further construction in which the counterweighted cover 3 is pivoted on a horizontal shaft 33 on which is mounted a sprocket 35 connected by a flexible chain 36 to a second sprocket or a pulley 37 fixed on the mast 10 of the bucket-hoisting mechanism.
